The fewer average carbon number of n paraffin in diesel is, the lower cold filter plugging point is.
柴油中正构烷烃的平均碳数越少，冷滤点越低。
Biodiesel is easy to crystallize under low-temperature because of high solidification point (SP) and high cold filter plugging point (CFPP).
然而生物柴油凝点和冷滤点很高，低温情况下容易结晶析出，堵塞发动机的管道和过滤器而无法正常使用。
It is known that setting point and cold filter plugging point of low pour point diesel with cold flow promoter can reverse during the storage and use process.
加入低温流动性能改进剂生产的低凝柴油，在储存和使用过程中存在凝点、冷滤点反弹回升现象，因此对辽河原油的常压柴油、加氢裂化柴油进行了加剂研究。
